The Raspberry Pi has been a huge success story for Britain, giving millions of people an affordable way to tinker and learn with pocket-sized hardware. Now, the BBC is hoping to make a similar impact with the "Micro:bit." Like the Raspberry Pi, this tiny computer has been created to help youngsters learn the fundamentals of programming and computer construction. Today in London, the broadcaster unveiled the Micro:bit's final design -- a rectangular, credit card-style board measuring 4cm by 5cm -- and some of the all-important hardware features. These include 25 red LEDs, which can show messages and facilitate games, two programmable buttons, an on-board accelerometer and magnetometer. The device also offers Bluetooth LE connectivity, a microUSB slot and five input and output (I/O) rings that can be hooked up with crocodile clips and 4mm banana plugs. It's been a while since the original BBC Micro was considered cutting edge, but even so -- this new device is roughly 18 times faster and 67 times lighter than its spiritual predecessor.

ARM's been championing the Internet of Things for several years now, and for good reason: it's poised to win big as more devices tap its low-power chips. Last year it unveiled an Internet of Things platform, now at Computex it's targeting device makers and its chip building partners by announcing an IoT subsystem for its Cortex-M processors. Basically, that means it'll be easier for semiconductor companies to take ARM's designs and build chips that are ideal for connected devices, while also integrating ARM's mbed IoT platform. The company also announced its new "Cordio" low-power radio, which runs below 1 volt and packs in Bluetooth 4.2. Dipesh Patel, ARM's EVP of technical operations, noted that Cordio will be ideal for extremely low-power connected devices like beacons. All of this may seem a tad dull, but if ARM wants the whole Internet of Things ecosystem to take off, it's essential for ARM to make it as easy as possible to build for it.

There's been a lot of talk about how phones from certain manufacturers can sense when you're running benchmarking software and will artificially inflate their performance accordingly. It's been a problem for some time now, but the industry appears to be finding its own ways of dealing with the issue. ARM, the outfit that designs the bulk of the smartphone industry's chips, has teamed up with British startup GameBench to make benchmarks not only more honest, but also a lot more understandable.

You've probably heard no end of hype for 4K video on TVs and computers, and now it's about to invade your phone... at least, so long as ARM has its way. The company just took the wraps off of Cortex-A72, a processor reference design that promises a huge boost to computing power, especially when graphics come into play. Thanks to updates that include optimizations for an efficient 16-nanometer chipmaking process, 30 percent more memory performance and an 80 percent speedier graphics core (the Mali-T880), the A72 is about 3.5 times more powerful than ARM's earlier Cortex-A15. That's beefy enough to record 4K video at an extra-smooth 120 frames per second -- many current smartphones only manage 30FPS at best. You should get "console-class" gaming, too, and there's a promise of Google Now-style natural voice commands that don't depend on a distant server to interpret what you're saying.

At Expand NY in November, DARPA Director Arati Prabhakar talked about the erm, friendlier projects the agency is funding, including a mind-controlled robotic arm tested by Pittsburgh native Jan Scheuermann. Her test run has recently ended, but the University of Pittsburgh researchers in charge of project have published a paper detailing how much the limb has improved over the past two years. Before they took off Jan's implants, she could already move not just arm itself, but also its wrist and fingers -- she reportedly even beat her brother at a rock-paper-and-scissors game. "Overall, our results indicate that highly coordinated, natural movement can be restored to people whose arms and hands are paralyzed," said Pitt School of Medicine professor Andrew Schwartz, Ph.D.

Qualcomm is sitting pretty right now. Its Snapdragon processors and cellular chips are present in most of the big-name mobile devices you can use today, whether it's the Nexus 6 or the iPhone. However, the company isn't content to stop there -- it just confirmed plans to launch its own line of server processors. CEO Steve Mollenkopf isn't offering many details just yet, but it won't surprise you to hear that these heavy duty CPUs would be ARM-based like their mobile counterparts. There's no timing yet, either, although the exec adds that his firm is already "engaged with customers."

LG has been trying for years to catch up to Samsung and Apple in phone sales, and its next step on that path is to make a device with an LG CPU inside. The G3 Screen phone that it's releasing this week in Korea will have an eight-core "NUCLUN" (pronounced NOO-klun) processor, based off of an ARM big.LITTLE design similar to Samsung's octacore Exynos chips. NUCLUN has four 1.5GHz cores for the tough tasks, and four 1.2GHz cores for easier stuff that help it save on battery life. Otherwise, there's also a 5.9-inch 1080p screen and support for the new, faster LTE-A networks that download at up to 225Mbps. Until now, LG's phones have mostly relied on Qualcomm chips for their processing needs, but Dr. Jong-seok Park believes going its own way will help the company "achieve better vertical integration" and greater flexibility going forward. Of course, we're wondering when a NUCLUN-powered phone will go on sale outside of Korea, but considering the progression of Exynos, that could take a while.

It's the year 2014, and we've yet to have our flying cars and commuter jet packs. But we do have a glimpse of the future with the advent of the "internet of things." It's essentially the idea of connecting everyday objects -- be it thermostats or kitchen appliances -- to the web, in an effort to make our lives easier. As wonderful as that sounds though, development of new IoT technologies can be slow, due in part to the multiple different protocols in existence today and how tiresome it is to create an ecosystem from scratch.

That could soon come to an end, however, thanks to ARM. The chipmaker has just announced a brand new IoT-specific device platform that includes both a free operating system (tailor-made for ARM's Cortex-M processor based devices, of course) plus a server-side software product that ties it all together. Based on the mbed hardware and software ecosystem, the platform basically gives manufacturers the tools and building blocks necessary for IoT devices and services, thus making it that much faster and cheaper for them to bring their ideas to fruition.

If you have any smart device -- be it a phone, tablet, router, wearable or otherwise -- there's a good chance ARM's Cortex lineup is responsible for the brains behind the scenes. The company just announced the latest processor in its M-series, which is a set of low-power processors capable of handling embedded devices like smart home appliances, drones, automotive and wearables, which is focused on making said devices even more powerful. The M7, as it's called, comes with a 400MHz processor, packing more than twice the punch as the 168MHz M4 that came before it (and will continue to be available to manufacturers). It comes with support for more displays, motors, voice controls, connectivity, audio performance and improved GPS accuracy. In other words, the infamous Internet of Things should become even stronger and more powerful. ARM says that manufacturers are already building devices with the chip embedded, so it won't be long before we get to see if the extra power actually makes a difference in our everyday lives.

NVIDIA set out to claim the Android performance crown when it unveiled its 64-bit Tegra K1 processor at the start of the year, and it's now ready to explain why it expects to come out on top. The chip's two Project Denver cores will have an edge partly because they'll optimize code on the fly -- they'll break down big instructions into tiny, super-efficient functions that can be recycled as often as necessary. The company expects roughly twice the speed it would get from ordinary code, making the 64-bit K1 faster than you'd expect just by looking at the hardware. It should tout "significantly higher" performance than current four- and eight-core mobile CPUs, and run as well as some PC processors; be prepared for more Tegra-powered laptops and high-end tablets.

You can pick up a Chromebook for a dirt-cheap $200, if you know where to shop. However, there are now signs that these Google-powered portables could get even cheaper. MediaTek has contributed code to Chromium OS (the base for Chrome OS) for a test device with an entry-level ARM Cortex-A7 processor -- a big step down from the relatively inexpensive Cortex-A15/A7 hybrid that Samsung uses, not to mention the Intel Celeron chips in other Chrome devices. Theoretically, this leads to Chromebooks and Chromeboxes that cost significantly less than $200, albeit after a big speed hit. Just as with phones and tablets, a Cortex-A7 system is likely to be pretty sluggish.

Want proof that you don't need big, specialized equipment to produce a mind-controlled robot arm? Just look at a recent University of Toronto student project. Ryan Mintz and crew have created an arm that you control using little more than a brainwave-sensing headset (which is no longer that rare) and a laptop. The team's software is smart enough to steer the arm using subtle head movements, such as clenching your jaw or winking your eye; it also knows when you've relaxed.

Humans are good at catching fast-moving objects -- just ask any baseball fan. Robots typically lag behind, however, which is why the École Polytechnique Fédérale de Lausanne (EPFL) has developed a robot arm with the reaction time needed to catch just about anything. After learning the basic concepts by imitating human behavior, the machine uses its cameras to predict the path of a flying object and grab it in less than five hundredths of a second -- roughly as fast as it takes you to blink. It can even adapt to objects whose center of gravity is likely to shift around, such as a half-full drink bottle.

In some corners of the world, even starter smartphones like the ZTE Open are too costly; basic cellphones such as the Nokia 105 thrive in areas where whole families can only afford one device. However, ARM believes that smartphones will soon be within reach of just about anyone. While it's possible to make a $25 Firefox OS phone today, ARM now expects to see a $20 Android phone within the "next few months." It might not actually be possible to go cheaper using current manufacturing techniques, the chip designer says.

Typically, you can't reuse many parts when you switch processor technologies; if you change chips, you change the entire motherboard at the same time. That won't be true for AMD in the future, though. It's working on a common chip framework, Project Skybridge, that will let 2015-era ARM and x86 system-on-chip processors share the same pin layout. In other words, a basic motherboard design could handle both CPU types.

Until yesterday, the world record for fastest time in solving a Rubik's Cube was 5.27 seconds, which was set in the fall of 2011 by a Lego robot named Cubestormer 2. Thanks to the machine's successor (aptly named Cubestormer 3), the time to beat is now 3.253 seconds. The robot, which is the third in a series of automatons designed solely for the purpose of solving the Rubik's Cube ASAP, is powered by an octa-core Samsung Galaxy S4; it's got four high-performance ARM Cortex-A15 cores and four lower-intensity Cortex-A7 cores running the show, each one managing its own Lego Mindstorms actuator.

Version 13 of XBMC's media center software, codenamed Gotham, is now ready for your official beta-testing pleasure. The foundation -- which started the project for the Xbox and spawned apps like Plex and platforms like Boxee -- kicked off work on the update nearly a year ago. It said that many of the qualms from version 12 (Frodo) users have been addressed. Most notably, it now supports native hardware decoding on Android for x86 and ARM platforms, which should bring smoother playback for formats like Blu-ray. Other improvements include support for more 3D formats (with the notable exception of 3D Blu-ray), better touchscreen support, enhanced UPnP capability, "dramatic" audio engine improvements and easier setup. Though nightly versions have been available for a while, the company provided the usual caveats about beta software and the importance of backing up. If you're unperturbed by that, hit the source.

Well, that took awhile. Remember Instacube, the purpose-built digital photo frame designed to pull images directly from your Instagram feed? The Android-powered photo screen found itself short on both funding and manufacturing options last summer. These issues set production back almost a year, but come April 5th, it'll all pay off -- the first units are finally shipping out. Instacube's creators used the extra time productively, at least: the final hardware was redesigned to include speakers (to support Instagram video). Future updates will imbue it with the ability to stream content from Facebook, Vine, Flickr and other services, too. Kickstarter backers who opted for the white or classic models should get their units in the next few months, but the team says additional styles won't be available until production hits full steam. A bummer for sure, but hey, folks have waited longer to get Instagram.

Apparently, Freescale didn't think the diminutive Kinetis KL02 was tiny enough -- it just unveiled the KL03, the new world's smallest ARM microcontroller. At 1.6mm by 2mm, the Cortex-M0+ chip is 15 percent smaller than its ancestor. That's miniscule enough to comfortably fit inside the dimple of a golf ball, folks. Despite the shrunken profile, it's both easier to program and more energy-efficient. The size isn't just for bragging rights, of course. Freescale sees the KL03 helping out the internet of things, where a fraction of a millimeter can make a big difference. Companies can't start using the chip in earnest until it enters full production this June, but it may lead to very compact smart appliances and wearables once it arrives.

You might say the day is never really done in consumer technology news. Your workday, however, hopefully draws to a close at some point. This is the Daily Roundup on Engadget, a quick peek back at the top headlines for the past 24 hours -- all handpicked by the editors here at the site. Click on through the break, and enjoy.

We already have a hard time finding fault with processing power in the mid-range smartphones and tablets currently on the market, but that doesn't mean they couldn't be even snappier. That's the goal of ARM, which has announced the latest Cortex processors, known as Cortex-A17, to address not only mobile devices in the midrange market, but Smart TVs and Over-the-Top devices as well. The 28nm A17 comes with big.LITTLE (the architecture used in Samsung's latest octa-core Exynos chips) support, and promises a 60 percent boost in performance over Cortex-A9. It's also paired with a Mali-T720 GPU, which offers OpenGL ES 3.0 support and plenty of optimizations for low-end Android devices. While ARM doesn't specify an actual timeframe for release, it says that we should expect a huge push for the A17 in 2015; in a separate release, MediaTek also tells us that its newest octa-core processor comes with Cortex-A17 tech inside and will be available in the second half of this year.

On both desktops and servers, Fedora has seen popularity slip behind relative Linux new comers like Ubuntu and Mint. But Red Hat knows its strength lies in the enterprise, where its impressive security features have found love in the arms of sysadmins all over the globe. While we wouldn't say the release of version 20 (Heisenbug) is putting it ahead of the curve, it's certainly a valiant effort to future-proof the distribution. As the world preps for an explosion of ARM-powered servers, Fedora is finally adding support for the RISC-based processors to it's official channels. Until now support for ARM chips has been provided by unofficial community developers. Going forward, ARM will receive the same level of support that x86 chips from the likes of Intel and AMD have enjoyed for years. It also preps the distro for a market flooded mobile devices that emphasize form factor and battery life over raw processing power.

In another nod to its business customers, the OS has greatly improved virtualization support through both a new visual interface and the addition of virtual images crafted specifically for cloud computing services like Amazon Web Services and OpenStack. There, of course, are updates to desktop environments like GNOME and KDE, too for those more likely to install it on a home PC. Whether you're setting up an ARM server or just appreciate Red Hat's nod to Breaking Bad, you'll find full details of the Heisenbug upgrade at the source links.

Ever wonder how hot it gets inside of a cow's stomach? Neither have we, but if we ever had cause to find out, we can thankfully now do so wirelessly. Front and center in ARM's Internet of Things display at ArmTechCon this week we found Well Cow, a bovine health monitor that bobs around your cattle's rumen -- the largest of a cow's four stomach compartments. The sensor-laden pill lasts between 80-100 days inside the animal, transmitting pH and temperature data to a Bluetooth collar around the beast's neck. Data can then be retrieved using either an Android device or the company's own PC peripheral. We gave the app a quick whirl and were able to quickly discern the room's temperature and general air acidity with the touch of a button. (There appears to be a no cows rule on the show floor.)

It sounds like an unappetizing ordeal, but the setup actually prevents indigestion. By monitoring a cow's stomach acidity, farmers can catch digestive problems early, and adjust the animal's feed or medical needs before it becomes an issue. Micromanaging the animal's diet could also help maximize milk production. An odd thing to find in ARM's booth? Absolutely, but it certainly highlights the creative potential of the company's MBed development platform and what it could bring to the Internet of Cows Things.

Intel's largest chip manufacturing customer, Altera, has said that it'll soon be building chips there based on -- wait for it -- ARM technology. Its Stratix 10 SoC will contain a quad-core, 64-bit ARM Cortex-A53 CPU, which Intel confirmed would be the first of that type manufactured by anyone. By contrast, Apple's latest Samsung-built 64-bit A7 ARM chips used in the iPhone 5s are only dual-core. However, Altera's processors, which will be fab'ed with Intel's advanced 14nm tech are destined for networking equipment only and won't compete with the likes of Qualcomm and Samsung for smartphones. In any case, Intel's just a gun for hire with its biggest competitor's tech, so it would be unwise to draw any conclusions -- after all, the chip giant has its own Clover Trail to follow.
